Earbuds have a habit of getting tangled and annoying when you toss them in a bag. Luckily, you can keep them organized with a standard chewing gum container.

Instructables user Kris T. shows you how it's done. The project is pretty straightforward, but I love that it keeps the the headphones organized while still letting you use them. He used a bead to keep the aux jack from sliding into the box, and a paperclip to control how much length he can pull out of the other side. The only downside is that you have to manually repack the spare wire once you're done, but that still beats dealing with tangles. Be sure to check out the source link for complete instructions.
